Better Off Dead by Lee Child & Andrew Child (2021) Delacorte Press

In which Reacher walks into a setup of an ex-Army intelligence officer who has set a trap to find her missing brother.  After convincing her he doesn’t know anything about it, he hides, and watches two thugs fall for the trap.  She thinks her brother is dead.  Reacher thinks otherwise.  There is a man who makes anything, including bombs for money.  He is willing to exert control over this out of the way town and follows-up his threats with murders.  The brother was working for this man.  Reacher is intrigued enough to go after the man and get him and his thugs off the street.  This collaboration with Child and his son works seamlessly.  The pace is just as intense as any of the previous books.
